SB Components Pico Air Monitoring Expansion Board
Air quality monitor for Raspberry Pi Pico with laser dust sensor, OLED display, real-time PM1.0/PM2.5/PM10 readings.
The SB Components Pico Air Monitoring Expansion is a portable, open source add-on board for the Raspberry Pi Pico, designed to provide detailed real-time information on particulate matter in the air. It is equipped with a high-contrast 0.91-inch OLED display that conveniently shows monitoring results on the board itself.
At the heart of the expansion is the PMSA003 digital laser dust sensor, which delivers accurate real-time readings of PM1.0, PM2.5, and PM10 concentrations. The sensor measures particles in the range of 0.3 to 1.0, 1.0 to 2.5, and 2.5 to 10 micrometres, and operates reliably across a temperature range of -10°C to 60°C, making it suitable for a wide variety of indoor and outdoor air quality monitoring applications.
The board communicates with the Pico via a UART serial interface, and it operates at 5V. It features a standard 40-pin header for direct connection to the Pico (the Pico requires male headers soldered with pins pointing down). Additionally, external GPIO breakout pins are available, allowing you to connect further peripherals and expand the functionality of your project.
With compact board dimensions of 92x68mm (WxD), the Air Monitoring Expansion is easy to integrate into your own enclosure or mounting setup. The kit includes the Air Monitoring Board only; the Raspberry Pi Pico is not included and is shown for illustration purposes only. Please verify your Pico’s header configuration before installation to ensure a secure and reliable connection.
